To a/ZZ whom) it may concern:

Be it known that we, OTTO LAUBFR and FRIEDRICH STOCK, subjects of the German Emperor, residing atEssen-on-the-Ruhr, Germany, have invented a certain new and useful Elevating and Sighting Attachment for Guns, of which the following is a speciiication.

The present invention relates to recoil-guns, and is especially applicable to field-guns in which the sighting device and mechanism for o erating the same are arranged on the crad e and in which the angle of elevation of the4 gun-barrel is fixed by .means of a screw elevatingmechanism.

`The object of thelinvention is to provide for an independent sight-line in such guns without essential alteration of the sighting device.

The invention is Illustrated in the accompanying drawings, in which- Figure l is a side elevation, on a scale smaller than that of the remaining vfigures, showing those parts of a gun having relation to the present invention. Fig. 2 shows a portion of Fig. l, partly in section. Fig. 3 is a rear view of F1g.\2, partly in section, on

line 3 Blof said figure and seen at a rightv an-v the sight-post is provided with adistanceand a notch-sight d2, Fig. 3. vThe scale d3, Fig. 3, and with teeth d, Figs. 2 and 3. A

The mechanism for iixing the angle of elevation of the gun preferably comprises two devices. The iirst elevating device consists of a hand-wheel e', a shaft E, a pair of cone' wheels e2 f 2, an externally-threaded hollow screw-spindle F, and an externally and internally threaded hollow spindle G, the Object of this first elevating device being to impart to the gun-barrel an angle of elevation correspondin seconde evating device consists ofthe screwt-post D, which carries a sight-tele' l and the sight-post D are to the distance of the mark. The

spindle G, a nut H, a pair of conevheels h2 ft2, a shaft J, and a hand-wheel i", the obj ect of this second elevating devicebeing to adjust simultaneously the elevation of the gun-barrel and the rear sight. The carrier K for this second elevating device, Fig. Sjprovides the connection between both elevating devices and the mount C, on which it bears through trunnions kf, which permit it to partake in the swinging movements of the elevatingdevices when the angle of elevationis adjusted. The ir'st elevating device islinked to the cradle A by means of an approximately T- shaped bearing-piece M M MMs, the shanks M M of which form hollow trunnions` vin which are provided bearings for the shaft E. The said hollow trunnions rest in bearings X, (see also Figs. l and 2,) open at the bottom, secured to the cradle, and closed by bearingj lates P Q. The shank M2 of the T-'shapcd y caring-piece serves as a bearing-pivot for the spmdle F. To the free end of the shank M2 is screwed a head m, which, together with the part M3 connecting the Shanks M M', pre-4 vent sliding of the spindle F relatively to the shank-M2. The part M3 is provided` with recesses for the cone-wheels ezfg. The spindle and isintegral with the cone-wheeljl, which meshes with the cone-wheel'ez, that isnonrotatably secured on the shaft E. ,A shoulder on shaft E and one of the bearings for the samedprevent horizontal movement of the cone-wheel e2 relatively to the shaft E. One end of the shaft E carries the'handwheel e. while the other end of the shaft ter-l minates in a cone`-wheel.e3, that meshes with a'cone-wheel t3 of a shaft T. (See also Figs.

ing R, inclosing the cone-wheels e3 t3, and in a projection@5 (sec also Fig. 2) ol the guideiece a,il for the sight-post. The casing R is Integral with the bearing-casing Q.- The end of the shaft T that is opposite to the cone-, wheel t? vcarries a conical right-handed worin t4, thatr meshes with the teethd of the sightvpost D. The pitch of the screw-threads of the spindle F and the proportion between the cone-wheels @2f and e3 t3 and the worin-gear are so selected that when the 'hand-wheel c3 is turned the sight will be adjusted through the same angle as the gun-barrel, butin the opposite direction. g

sight of 0.

grooves g2 g3, Figs. 3 to 5, into which project Figs. 3 and 4, or 7c?, Fig. 5, secured to the carrier By'means of the feathers k2 k3' the screw G'is heldfrom rotation around its own axis, while the screw may move'longitudinally' relatively to the carrier K. The screw G is inclosed lbythe nut H, that. is arran ed rotatably but non-slidabl in theA carrier. The nut H is intergal wit the cone-Wheel '72.2,' with which -meshes the cone-wheel 2, secured on the shaft J The and is j ournaled in the lefthand hollow trunnion c,

Fig. 3, of the carrierK and in the jack S, se-- cured to the mount C.

The relative positions of the different parts as represented in the drawingscorrespond to an angle of elevation of 0 y For directing the sightline'on `the target the second elevating device is made use of.

When the hand-Wheeli ofthe second device. is turned counter-clockwise, the nut H willl turn throu h the medium of the shaft J and By this turning of nut H the screw G, Whichis prevented from rotation by feathers k2 7c3, will'be screwed downward 1n .said nut. This movement -of screw Gis simultaneously transmitted, through the medium of the spindle F and the T-shaped bearing-pieceM M M2 M3, to the cradle or the gun-barrel and to the sight-post in the sense that a corresponding movement of'elevation takes place in the gun-barrel andthe sight. The carrier K makes lat the same time a slight swinging movement around the axis' of its trunnions c,and the T-.shaped bearing-piece M M M2 M3 turns sli htly around the axis of its Shanks M M; Igf the hand-Wheel i is turned counter-clockwise, the directionof movement of the different-parts will be reversed.

In order to impart tothe gun-barrel an elevation .correspondi'n to the distance from the mark, the first e evating-device is made use 'of. Whn the hand-wheel e ofthe first device is turned counter clockwise,

dle- F srotated through the medium of the shaft E and the cone-wheels e2 f2, and the spindle F is screwed downwardly into the spindle G, that is prevented from rotation around its axis by the feathers 7a2 7c?. Through the medium of the T-shaped bearing-piece M M M2 M3 the movement of the spindle F is transmitted to the gun-barrel and the rear part of the gun-barrel is lowered. The rotation of the shaft E simultaneously causes the sight to move through the same angle as the moveand to an angle of the spin-A direction, through the medium ofthe cone- Wheels eats, the shaft T, and the'worm-gear` ade barrel, indicates on the scale d3 the yamount of' elevation or the range 'corres ondingto such elevation. If the hand-W eel is rotated ment of the gun-barrel, but in the 'opposite i clockwise, the rear part of the gun is elevated A, and the sight is moved downwardly' at the same angle as that of the movement'of the 'The two elevating devices may of course be regarded as forming a single device, to the spindle F` of which a sliding movement only or a sliding and rotating movement is im'- parted, according to the manner whiclifthe devicels operated. t

Having thus described the invention, V4the following is what is claimed as new:

1.` Asight'ing andelevating attachment fo guns 4comprising a plurality of coaXially-ar- I ranged screw-spindles, a sight, vmeans mounted independent of the screw-'spindles and through which the sight-is controlled,','and
